JOSEPH GOLDSTEIN, OF BROOKLYN, NEW YORK.

CHAIR-SEAT.

Specification of Letters Patent.

Patented May 6, 1919.

Application led April 13, 1918. Serial No. 228,339.

To all whom t may concern:

Be it known that I, JOSEPH GoLns'rEIN, a citizen of the United States,and resident of lthe borough of Brooklyn, in the county of Kings andSta-te of New York, have invented certain new and useful Improvements inChair-Seats, of which the following is a specification. y This inventionrelates to chair seats and is directed particularly to cushion seats inwhich provision is made for resiliency and durability.

In prior constructions of cushion seats for chairs many diiiculties havebee-n encountered due to the cushion becoming hard after a short. periodof use or due to the breaking through of the material at the bottom. Mymain object in this invention, therefore, is to provide a cushion seatconstruction which shall be strong, durable and comfortable.

Another object of my invention is to provide a cushion seat of thischaracter wlich may have these advantages and yet be very simple inconstruction and inexpensive to manufacture.

A further object is to provide a separate cha-ir seat frame cushion seatwhich may be easily attached to the ordinary chair such as the kindknown .as the dining chair.

A still further object of my invention is to provide an improvedcomfortable and resilient bottom for cushion seats of the characterdescribed.

Further objects and advantages of this invention will appear from thedetailed description and the features of novelty will be particularlypointed out in the claims.

I am aware that attempts have been made to provide chair seats withmeans for rendering them more or less resilient. The prior constructionsresorted to in the main have provided coil springs in the body of thecushion to render the seat more or less resilient, but these beingdisposed in the body of the cushion cause discomfort and further cutthrough the bottom eventually ruining the cushion. Straps of fabric orresilient material have been used as supports for the filling of thecushion but after a little use the .filling is compressed .against thesestraps of the bottom, and the cushion becomes hard, and eventuallybulges out 'at the bottom and the chair becomes unsightly.

. In the present invention I provide a cushion seat which accomplishesthe aforementioned objects, and is free'from the difficulties had wlththese Iprior constructions.

\- In the dra-wing accompanying this invention,

Figure 1 is a plan view partly broken away of a. cushion seat embodyingmy invention in place in a chair and showing the iniproved resilientbottom;

Fig. 2 is a section taken along line 2-2 of Fig. 1; and

Fig. 3 is a plan view of the cushion seat shown in Fig. 1 viewed fromthe bottom.

Referring in detail to the drawing l0 indicates a chair seat comprisinga preferably wood frame, consisting of side members 11 secured in somesuitable manner to the front and end members 12 and 13 as by means ofthejoints 14. Stretched across the opening 15 is the preferably metalbottom 16 which serves as a resilient support for the cushion. Thisbottom consists of link members 17 interconnected by the plates 18 andis stretched across the opening in the wood frame and yieldingly heldthereto by the helical springs 19, These latter are anchored in plates2,0 suitably fastened in the corners of the wood frame as by the staples21 passing through perforations 22 in the plate. It will be seen thatthe springs are held in the perforations in the ends of the plates 20and perforations 23 in the end plates of the resilient frame. Theplates20 are secured at. the corners of the wood frame and bridge the end andside members that join at the corner. These plates thus serve as anchorsfor the coil springs and when the resilient bottom is stretched inplace, at the same time `help hold the side and end members of the woodframe together, thus cooperating with the joints 14, and preventing .themembers of the wood frame from becoming loose.

A piece of burlap or the like material 24 covers the resilient frame andthe filling or padding 25 for the cushion is disposed therebetween andthe usual cover 26 of upholstering material such as leather. rI hecushion seat is made up as a separate member and may be secured in anysuitable manner to the chair frame. This I secure to the legs 27 ofthe'chair the brackets 28 on which the cushion seat rests and may beattached thereto by any suitable means such as dowels or screws 29. Itwill be noted that in the form shown I cut out the side pieces `at theends as at 30 to provide shoulders whereby the cushion sent may set intothe chair frame and rest on the side piece 31 thereof.

In the ractice of -my invention I' may make upt e wood frame and theresilient bottom secured thereto as shown and described, and thecushionless seat members thus formed may be easily packed and shipped tochair manufacturers to be secured to chairs, or I may make up the frameand cushion complete, or chairs with my newly improved cushion seat.

Having thus described my invention, I claim as new and desire to secureby Letters Patent,

l. A chair seat frame for cushion seats comprising'l a frame memberhaving an Opening therein, a resilient bottom comprising a plurality oflinks and plates for interconnecting said links, anchor plates at thecorners of said frame and spring members held 2. A chair seat frame forcushion seats` .comprising .a frame member having side .25

pieces and end pieces joined together to inclose an openingtherebetween, a, resilient bottom comprising a plurality of links andperforated plates for interconnecting said links, perforated anchorIplates bridging the joints of said frame member, and helical springsheld in the perforations in said anchor plates and the end plates of thebottom to'yieldingly stretch 'the latter across said opening.

Signed at the city of New York in the county of New York and State ofNew York this 18th day of March A. D. 1918.
